The speed of a tennis ball can be determined by who is hitting it. An amateur or young child is not going to hit the ball as fast as a professional. At the professional level the ball can travel over one hundred miles an hour.
The speed of the ball can vary from slow serves with much spin to smashes that travel as fast as 112.5 kilometers per hour (70 mph).
It depends. If a tennis balls are hit with the same amount of force, then the dry tennis ball will travel faster and farther. However, if the two tennis balls begin traveling at the same speed, then the dry tennis ball will slow down more rapidly than the wet tennis ball. The reason is the added mass of water. It would take more force to make the wet tennis ball fly as fast as the dry, but the added mass also requires more force to slow down the wet ball.
Yes, of course. The material a tennis ball is made out of is porrus. That is why tennis balls go flat.
120 mph
It depends on the quality and conditions of the tennis ball. If the ball is used frequently, in the rain, or if it got wet, it could wear out in a few days.
Depends what surface your bouncing it on
It depends on many factors. How will the tennis balls be propelled? Will you hit both with a racquet? Will you shoot them from a potato cannon?
An example might be - Tennis is a fast-paced sport. Another example is - The tennis ball shattered the window.
An average fast ball in the MLB is about 92 MPH, Roger Federer serves a tennis ball at 135 MPH and Tiger Woods' ball speed is 170 MPH.
i think so it can go fast
As fast as a cheetah.
A rocket that is leaving the earth needs to travel at high speed to leave the earths gravity. The speed needed is approx 40,000km/h to break free from earths gravitational pull. An easy way to imagine this is if you pick up a tennis ball and throw it as fast as you can (eg, 90km/h) the tennis ball will travel up into the sky then will be pulled back down to the earth. Now you can throw the tennis ball at 20,000km/h. The ball would travel approx half way around the globe before being pulled back down to the earth. Now imagine you can throw the ball at 40,000km/h. The ball would leave the earth then travel around the earth in orbit.
